TurboFlush, i've just had my sierra 2.9 4x4 on the ramps.
the tag on the front diff says:
V85BB AA
29495 1A22
transfer box:
888T7L133 AB
C9P5A 9K10
don't know if that get's us any further forward?
anyway, i still don't have a workshop where i can start stripping these cars down. i will find out more about one on saturday, but that's delayed me by at least a week. hope you don't mind waiting for these parts?
